Update: 10:08AM: At ESPN Insider, Craig Custance has this quote from Mike Richter about the outdoor game:

“I’m a huge fan of this outdoor game. It gets back to the roots of our game. I’ll participate in whatever I can,” he said. “I grew up idolizing the Flyers. We had a couple wars against them many times … to get another kick at that is a very cool thing. I’ll definitely be there one way or another.”

Original Post: 11/14/11: 8:22PM Jesse Spector tweets that Rangers legend Mike Richter is undecided on whether he will play for the team in the Winter Classic Alumni game.

Spector also says that Ron Duguay will play for the Rangers.

Duguay was a lock, his presence on the broadcast and around MSG made him one. With Richter, it depends on how he is feeling and whether he thinks playing will bring about the headaches that ended his career. Keith Primeau won’t play for the Flyers because of post concussion issues he still has.
